Massive Amounts of Water in the Cosmos

One of the things that has entered the debate about life in space has been the presence of water. Astronomers have found methane, ethane, and other compounds in oceans on other planets and moons in our solar system. Unlike water, they are not polar molecules. The polar structure of water makes it an apparent necessity for life. Scientists have debated about whether water has existed or does now exist on Mars, our Moon, or one of the many moons of Jupiter and Saturn. Now there is evidence of massive amounts of water in our solar system.

We have posted before about NASA’s “Astronomy Picture of the Day” website (apod.nasa.gov). On January 15, 2021, the page showed this picture taken by the New Horizons spacecraft on July 14, 2015, as it flew by Pluto. The photograph shows areas of frozen nitrogen and carbon monoxide. It also shows massive amounts of water ice frozen into mountains reaching up to 11,000 feet (3,353 m), which is comparable to mountains on Earth.

There is more and more evidence that, at least in our solar system, water is quite common. Because of the temperatures in the outer planets, that water is in a frozen state. Liquid water has a very narrow range of temperatures, and that means the zone in which a planet can have liquid water is very small. Because of that, life on another planet is improbable, but the potential for humans establishing or supporting life elsewhere is relatively high.

Verse two of Genesis 1 tells us that the early Earth had water in the liquid state: “And the spirit of God moved upon the face of the waters.” Massive amounts of water apparently dominated the planet. Verse six tells us that there was “a firmament in the midst of the waters” that divided the waters. It isn’t until verse nine that dry land appears. The keyword in these verses is the word translated firmament in English. The Hebrew word used here is “raqia.” It is used nine times in Genesis 1 and eight times elsewhere in the Old Testament. Four of those eight are in the visions of Ezekiel 1:22-26.

The Bible’s economy of language leaves us to understand the “firmament” from its context. The most accurate understanding is what, in modern terms, we would call an “interface,” a zone of change. In many cases, that zone is the atmosphere, so in verse 20 of Genesis chapter one, we have birds flying in the firmament. Genesis 1:14-15 tells us that the Sun and the Moon became visible as the darkness (Genesis 1:2) of the cloud cover (Job 38:8-9) in the firmament cleared. Ezekiel saw his chariots in the firmament.

The discovery of mountains of frozen water elsewhere in the solar system indicates that the original cosmos had massive amounts of water, as Genesis 1:6 implies. It also tells us that when the Earth’s temperatures settled to between zero and 100 degrees Celsius, the water became seas covering the planet. This is one more evidence for the integrity of the Genesis account as it describes the creative design of God, simplified so that all humans can understand it.

Fake Asteroids and Space Junk

Politicians and the media often use the word “fake” in all kinds of dubious ways. Now we can apply the word to an asteroid known as 2020 SO (Space Object). It seems that this fake asteroid is just space junk.

There has been concern among astronomers for many years about the large number of rocks in our solar system. Right now, the International Astronomical Union’s Minor Planet Center has almost a million identified asteroids and comets, some of which could strike the Earth and cause massive destruction. The idea is that by cataloging these objects, we can know if any are on a collision course, so we might intervene to alter the trajectory.

It turns out that at least one of the cataloged asteroids is a fake asteroid. It is actually space junk. A NASA scientist determined that it is the upper stage of a Centaur rocket that put NASA’s Surveyor 2 lander on its way to the Moon in 1966. This rocket is just under 32 feet long and 10 feet in diameter and traveling at 1500 miles per hour. Another fake asteroid has turned out to be the third stage of the Saturn five rocket, which NASA launched in 1969 during the Apollo 12 mission.

Scientists are concerned about the amount of material that humans discard. That includes plastics that clutter the oceans and provide a constant headache at landfills. Chemicals dumped into rivers and lakes have had a very destructive effect on fish and other life forms, including humans. Space is also becoming more and more cluttered with human space junk. The material left from space launches is becoming a hazard to communications satellites and even space vehicles, including the International Space Station.

The need to make full use of everything and recycle is vital to our safety and health. When a terrible disease or deadly accident occurs, many people blame God. But more and more, we see that human neglect and carelessness causes most of our problems.

The Cords of Orion – What Are They?

In the book of Job, God asks the character Job, “Can you loose the cords of Orion? Can you bring forth the constellations in their seasons?” What are the cords of Orion?

Since ancient times, people imagined that the asterism in the Orion constellation resembles a hunter holding a sword. The sword appears to consist of three stars. However, if you look closely, you can see that the central star is a little “fuzzy.” With a telescope, you can see that it’s not a star, but a nebula.

The picture of the Orion Nebula was taken by NASA’s Hubble space telescope. Nebulae are star factories, where clouds of dust and gas are collapsing to form stars. At “only” 1344 light-years from Earth, Orion is our closest star factory. Astronomers have observed about 700 stars in various stages of formation in the Orion Nebula.

There are many more nebulae where stars are being made today, as they have been since the universe began. These star factories are responsible for creating the billions of stars in our Milky Way galaxy and beyond. They show that God is not a magician who pulls a universe out of his sleeve. God is an engineer who has designed an amazing system that makes possible everything we can see, and much more that we can’t see.

As we look at the cords of Orion, here is something to consider. God, who is outside of time, created a star factory in time, which then generated a star we call the Sun. Then He provided a home for us on the third planet from that star where we can look up and see star factories, like the Orion Nebula, at work.

Radiation Levels on the Moon

God created planet Earth for us to live on, and He designed us with what we need to survive here. The more we learn about conditions elsewhere in the solar system, the more we see how unique Earth is. Recently we have seen research data concerning radiation levels on the Moon. Our studies reveal that astronauts on the Moon could get up to 1000 times more radiation than what we experience on Earth.

Dr. Kerry Lee at the Johnson Space Center in Houston has analyzed data from a Chinese-German team. The Germans used data retrieved by a Chinese lander named Chang’e 4. They compared it with data from a NASA orbiter that has been circling the Moon for over ten years. The two sets of data agree 100%. The primary risk factor for humans is cancer. The message is that if humans try to exist on the Moon, they will need thick-walled shelters for protection.

We take for granted the romantic idea that humans can wander around space, looking for new information about the stars and planets. In doing that, we fail to realize how carefully designed the Earth is to avoid the dangers of radiation in space. Astronauts in the International Space Station get three times less radiation than the radiation levels on the Moon.

Our upper atmosphere and magnetic field help to shield us from radiation. God carefully designed the Earth with features to protect us from radiation from the Sun and other stars. Proverbs 8:22-30 finds wisdom speaking about the creation. The more we look out into space, the more we see the necessity of wisdom in making a world where we can live safely.

Our Atmospheric Shield

One of the fantastic and vital features of planet Earth is our atmospheric shield. We have often mentioned the NASA website Astronomy Picture of the Day (apod.nasa.gov). Every day NASA posts a different astronomy picture to show us something of the cosmos. This is an excellent service because most of us don’t have access to giant telescopes, and we can’t see light in wavelengths outside of the visible spectrum.

On September 12, 2020, NASA’s posting showed a time-lapse series of pictures taken by the New South Wales observatory in Australia. This observatory is located at 33 degrees south latitude in an area with minimal light pollution, so there is minimal obstruction of the night sky. The pictures were recorded on 372 nights and run like a movie. What you see are sporadic meteors, fireballs, meteor showers, and even a lightning sprite. The series shows over 1000 meteors.

Remember that this picture sequence shows a relatively small area of sky. This does remind us that there is a constant rain of dust, pieces of rock, and other debris coming down upon our planet. People working with communication satellites are well aware of this because of constant damage to the orbiting objects. For those of us on Earth’s surface, our atmospheric shield burns up most of the solid space material. We don’t have to worry about getting hit by space debris or getting sandpapered by the small dust particles coming from outer space. That is just the solid stuff. Our atmospheric shield also refracts away non-solid radiation such as x-rays and gamma rays.

Providing a place where life can exist is not as easy as some think. One of the reasons we are not finding life in outer space is that designing and implementing our atmospheric shield was vital for the existence of life, and doing that was not simple. It required intelligence and a carefully implemented design. The simple statement, “In the beginning, God created the heaven and the Earth” doesn’t tell us the incredible difficulty of doing that.

Look Through a Telescope

Modern technology has given all of us a chance to look through a telescope and see what is in outer space. In the “old days” the only people that could look outside our solar system were astronomers who had access to powerful telescopes. Now all of us can look out and see what lies beyond our solar system without buying a telescope because the pictures are available to us on the web. If you go to apod.nasa.gov you can see pictures taken through the world’s largest telescopes. The picture for August 7, 2020, is of the Pipe Nebula. As I stare at the picture, I am awestruck by the number of stars in the cosmos.

Why are there so many? Why is the cosmos so big? If you believe that God created it all, why did He create billions of stars in billions of galaxies? If Earth is the only place with life, why are there other planets, other stars, other solar systems? Why is space full of matter like the Pipe Nebula? Obviously no one knows the answers to all these questions. Anyone who gives a dogmatic answer that invalidates the existence of God is claiming to have more knowledge than the rest of us. Those who claim the pictures are fakes or artistic works have not taken the trouble to go to an observatory and look through a telescope. Most observatories have arrangements that allow the general public to do that. We have no excuse for doubting the credibility of the pictures.

Whether you are an atheist or a religious fundamentalist, your viewpoint makes massive assumptions. Here are a few things you should know, that may make you uncomfortable:

No observation made has ever challenged the basic biblical claim that there was a beginning and that it was caused. You can argue about what the cause was, but attempting to deny that there was a beginning, puts you at odds with the observations and the laws of physics–even at a quantum level.

There is no support for the assumption that planet Earth is the only place in the universe where life exists. If there is life elsewhere, God created it, and the Bible does not say the Earth is the only place where God created life. However, the distances are so huge that we will never know if this is the only place–at least not in our lifetimes. Many years ago, I debated an atheist on a talk show with Larry King. A listener called in and asked the atheist and me “What would you two do if a space ship landed in plain sight and a little green man got out and asked, ‘Has Jesus been here yet?’” That raises all kinds of issues, but it makes the point. By the way, the atheist’s answer was, “Punt.”

As we look through a telescope we are looking into the distant past light-years ago. No one knows what the distant future holds. Could it be that God wants humans to colonize the cosmos? Perhaps our vision of God’s kingdom is too small. Every time I look at one of those pictures of star fields or look through a telescope, I am reminded of Psalms 8:3-4 “When I consider the heavens, the work of your fingers, the moon and the stars which you have ordained: What is man, that you are mindful of him?”

Stars and Habitable Zones

The more scientists study Earth and other objects that surround us in space, the more variables we realize must be carefully controlled for life to exist. Many times before, in our posts, our videos, our books, and our printed quarterly, we have discussed the growing list of parameters that must be carefully chosen. NASA posted a graphic of different kinds of stars in the cosmos and whether they could support life. This picture of stars and habitable zones adds to our understanding of the unique qualities of our Sun.

Water is essential for life. Science defines life as having properties such as moving, breathing, eating, reproducing, and responding to outside stimuli. We don’t discuss “rock people” or “gas people” because they don’t fit that definition. For that reason, scientists are interested in stars and habitable zones–the just-right “Goldilocks zone” surrounding a star where water can exist as a liquid.

In their daily posting on apod.nasa.gov for January 31, 2020, NASA gives the distribution of Goldilocks zones for G spectral stars like our Sun, which are yellow, K dwarf stars, which are orange, and M stars, which are red. The other spectral groupings, such as blue stars, are not considered because of their high radiation levels and activity, which would make life impossible.

The most common type of star in our galaxy, making up 73% of all stars in the Milky Way, are M stars. These red stars have very active magnetic fields and massive radiation. Their Goldilocks zone would be minimal and very close to the star. Orange K stars make up 13% of the stars in the Milky Way. They have a modest Goldilocks zone but are fairly active with some radiation levels. Yellow G type stars like our Sun, make up only 6% of the stars in the Milky Way. These stars have very large Goldilocks zones, and they are very quiet compared to K stars.

As we consider stars and habitable zones, we must realize that the type of star is just the beginning of the variables necessary for a star system to support life. Other critical factors include the size of the star, the location of the planet relative to the star, and the shielding a planet has for protection from the radiation of the star. Also, the stability of the star’s location in the Milky Way is another factor that goes into a life-supporting planetary system.

Our existence is not a product of chance. The more we learn about the Earth, the Sun, and the stars and habitable zones within the Milky Way, the more we understand that the statement, “In the beginning, God created the heaven and the earth” is a massive understatement of what God did to make a place for us to exist.

Making Molecules on Jupiter

In recent years we have come to understand how God formed many of the elements that make up our world and our bodies. We watch stars producing new elements, and we realize that this system was designed by God to take the hydrogen produced in the beginning and continually make heavier elements by thermonuclear fusion. It is incredible to witness the power and design in a nova or supernova and to understand that this is God’s forge to make new elements. Now we have another picture of a design God has used for making molecules.

Molecules are combinations of atoms put together to produce a compound. Simple compounds like water and methane are difficult enough to produce. The huge molecules, such as amino acids that make up living materials, require a particular environment to form. Many of them have been found in space debris, but their origins are not clear.

The latest NASA report on Jupiter has given us some new understanding of making molecules. NASA’s robotic Juno spacecraft orbits only 15,000 kilometers above Jupiter’s cloud tops. Using new data from this spacecraft, astronomers have announced that Jupiter is apparently mostly liquid. It is not a ball of rock with a blanket of liquids and gases, as Earth-based observations seemed to indicate.

It’s hard to realize the size of Jupiter (2.5 times the mass of all other planets combined), its rapid spin rate (more than twice as fast as Earth’s), the amount of lightning that we observe, and the extreme temperatures are all working in a liquid. It indicates an environment similar to what we can create in our laboratories here on Earth to produce complex molecules. The Miller-Urey experiment of 1953 earned a Nobel prize for producing an environment in the lab capable of making molecules of amino acids. Now we see a location in space that duplicates much of Stanley Miller’s famous experiment. To be facetious, perhaps God should get a Nobel Prize for something that was operational long before any human existed.

The more we know of the creation, the closer we get to the Creator. Knowing His methods just increases our wonder at His power and wisdom.

Stirring the Pot – The Sun and Parker Solar Probe

If you do any cooking, you know that to be a successful cook, you have to stir the pot every so often. Not only does stirring the pot prevent the food from sticking to the bottom, but it also improves the flavor by mixing the ingredients. The Earth and its relationship to life is also a kind of pot. We are just beginning to understand how complicated the relationship is between the Sun and the various ecosystems on Earth that allow life and advanced life to exist.

In 2018 NASA launched a probe called the Parker Solar Probe to fly near the Sun and make measurements and observations. No space probe has ever been close enough to the Sun to gain much data, but this probe was designed to fill that gap in our knowledge. At this point, it is about halfway between the Sun and Mercury, the closest planet to the Sun.

The Sun has what are called switchbacks when the magnetic field briefly reverses itself. This reversal varies the amount of solar wind coming to the Earth. This variable wind compresses Earth’s atmosphere, stirring the pot, so to speak. The mixing of the gases makes changes in our atmosphere, which we can observe in the auroras. The magnitude of the switchbacks also affects our power grids and orbiting communication satellites.

It is obvious that the movement of materials in our atmosphere and the constant changes that take place are part of the solar system design. The new data may open doors not only to how we can protect our power grids, but it may give us further understanding of the origin and sustaining of life on Earth.

Stirring the pot is one more factor in the intricate design of our planet and solar system that makes life possible. When Proverbs 8 talks about wisdom being present before the creation, it speaks of things we are just beginning to understand. The more we know of the creation, the more we know of the Creator.

What the Mercury Transit Tells Us

What the Mercury Transit Tells Us Above is a photo of the Sun. If you look closely, you will see a small dot in the upper half near the right side. That is the planet Mercury, the closest planet to our Sun. Mercury made what astronomers call a “transit” of the Sun on Monday morning, November 11, 2019. In our area of the country, the sky was overcast, and it was snowing. However, Bill Ingalls of NASA took this photograph from his location in Arlington, Virginia. I find it interesting to consider what the Mercury Transit tells us.

What’s so special about Mercury passing in front of the Sun? For one thing, it doesn’t happen very often. Although the last time was only three years ago, the next time will be in 2032, but it won’t be visible from North America. The next Mercury transit visible in North America will be in 2049. Since Mercury is closer to the Sun, it passes between the Sun and us every 116 days. However, most of the time, it is either above or below the Sun from our view, and Earth’s atmosphere makes it invisible in the daylight.

Scientists used precision telescopes and equipment to study the transit. They can learn more about the atmosphere of Mercury as it is silhouetted against the Sun. Historically Sir Edmund Halley (1656-1742) watched a transit of Mercury and realized that it could be used to measure the distance between the Earth and the Sun. It occurred to him that a transiting planet would appear in different positions to viewers in different locations on Earth. Measuring the apparent shift between two distant Earth locations at the same time and applying a little math, one could calculate the distance to the Sun. In 1769, after Halley’s death, astronomers used a transit of Venus to calculate the Earth-Sun distance.

Think about what the Mercury transit tells us without even seeing it? Because of the fact that astronomers can know in advance the exact date and time of a transit of Mercury (or Venus), or a solar eclipse (when the Moon passes between Earth and Sun) we realize that the solar system is orderly. We can study the heavens and learn of the Creator. We can see His wisdom and design of our planet and the solar system in which it exists. We can know there is a God by the things He has made (Romans 1:20) as the heavens declare His glory (Psalms 19:1).
